1. Parts in the mold parting surface should not have holes on. -- -- -- -- -- solid trim parting surface grinding.
2. The injection pressure is too great, mediation to appropriate.
3. The gate set is not reasonable.
4. The back pressure of injection molding machine is too large, and the intensity of the mould does not apply, incurred after clamping, mold deformation, change the suitable injection molding machine.
Plastic trimming device principle:
Plastic trimming device is the disposal of austerity or hard plastic products of burrs of injection molding. Walked out to project installation, chassis, band installation, dust combined into one. Is a kind of surface is simple, does not occupy a space, to obey and tall spray cleaning machine. Projection data by high-speed reverse projection on the finished product, came the impeller of flake burrs and concave or burrs in the hole, can remove within short time. Project strength of intrusive, can mediate on the control panel of the inverter keyboard is proper number of reversal came. Flash machine spray chamber for band walks into a crew, indoor all laid rubber. Turn into the finished product in the band is stirring at the same time, by high-speed throw projection data collision and reach the result of uniform to remove burrs. By casting projection data, after the excellent circulation bits and pieces, the use of renewable from time to time, powdery burrs and relatively bulky attracted to collector projection data capture, screen mesh and relatively large burrs are filtered out. The two ends of the suction pipe, is equipped with humidifying nozzle. Excessive moisture can enhance spray cleaning result more, avoid dust adhesion, and can add the projection data of life.
